Abstract
BACKGROUND New permanent pacemaker implantation (new-PPI) remains a compelling issue after Transcatheter Aortic Valve Replacement (TAVR). Previous studies reported the relationship between a short MS length and the new-PPI post-TAVR with a self-expanding THV. However, this relationship has not been investigated in different currently available THV. Therefore, the aim of this study was to investigate the association between membranous septum (MS)-length and new-PPI after TAVR with different Transcatheter Heart Valve (THV)-platforms. METHODS We included patients with a successful TAVR-procedure and an analyzable pre-procedural multi-slice computed tomography. MS-length was measured using a standardized methodology. The primary endpoint was the need for new-PPI within 30 days after TAVR. RESULTS In total, 1811 patients were enrolled (median age 81.9 years [IQR 77.2-85.4], 54% male). PPI was required in 275 patients (15.2%) and included respectively 14.2%, 20.7% and 6.3% for Sapien3, Evolut and ACURATE-THV(p < 0.01). Median MS-length was significantly shorter in patients with a new-PPI (3.7 mm [IQR 2.2-5.1] vs. 4.1 mm [IQR 2.8-6.0], p = <0.01). Shorter MS-length was a predictor for PPI in patients receiving a Sapien3 (OR 0.87 [95% CI 0.79-0.96], p = <0.01) and an Evolut-THV (OR 0.91 [95% CI 0.84-0.98], p = 0.03), but not for an ACURATE-THV (OR 0.99 [95% CI 0.79-1.21], p = 0.91). By multivariable analysis, first-degree atrioventricular-block (OR 2.01 [95% CI 1.35-3.00], p = <0.01), right bundle branch block (OR 8.33 [95% CI 5.21-13.33], p = <0.01), short MS-length (OR 0.89 [95% CI 0.83-0.97], p < 0.01), annulus area (OR 1.003 [95% CI 1.001-1.005], p = 0.04), NCC implantation depth (OR 1.13 [95% CI 1.07-1.19] and use of Evolut-THV(OR 1.54 [95% CI 1.03-2.27], p = 0.04) were associated with new-PPI. CONCLUSION MS length was an independent predictor for PPI across different THV platforms, except for the ACURATE-THV. Based on our study observations within the total cohort, we identified 3 risk groups by MS length: MS length ≤3 mm defined a high-risk group for PPI (>20%), MS length 3-7 mm intermediate risk for PPI (10-20%) and MS length > 7 mm defined a low risk for PPI (<10%). Anatomy-tailored-THV-selection may mitigate the need for new-PPI in patients undergoing TAVR.

Abstract
SUMMARY
Objectives:
This study evaluated the effect of argon plasma treatment (PLA) and its combination with sandblasting (SAN), silanization (SIL), and hydrophobic bonding resin (HBR) application on the micro-shear bond strength of water-aged restorative resin composite to a newly placed composite, simulating restoration repair.
Methods and Materials:
Forty-five light-cured composite plates (20-mm long × 20-mm wide × 4-mm thick) were fabricated using a hybrid composite and stored at 37°C in distilled water for six months. The aged composite surfaces were treated according to the following experimental groups, varying both treatment and order of application: 1) SAN + SIL + HBR (control), 2) SAN + PLA for 30 seconds + SIL + HBR, 3) SAN + SIL + PLA + HBR, 4) PLA + SIL + HBR, 5) PLA + SIL, 6) PLA + HBR, 7) SIL + PLA + HBR, 8) SIL + PLA, and 9) PLA. After the surface treatments, four fresh resin composite cylinders (1.5-mm high × 1.5-mm diameter) of the same composite were built on each aged composite surface using a silicone mold. After water storage for 24 hours or one year, the specimens were submitted to shear bond strength testing. Data were statistically analyzed by two-way analysis of variance and Tukey's test (5%).
Results:
Groups 1, 2, and 4 presented significantly higher bond strength means at 24 hours, although group 4 did not differ from group 7. Groups 5, 8, and 9 demonstrated significantly lower means than the other groups. Even though groups 1 and 2 had a significant bond strength reduction after 1 year, they still demonstrated higher bond strength at one year of storage.
Conclusions:
While PLA application combined with surface treatment methods demonstrated high bond strength results, this treatment alone was not as beneficial as other methods that included SAN, SIL and HBR.
